A “migration report” from Apartment List details 7.9 percent of Seattle’s renters headed south to live in Portland, the most of any city.

“West Coast tech workers look to Portland as a more affordable alternative to San Francisco and Seattle,” the report reads. It goes on to note that “Seattle is the 2nd most common source of inbound searches to Portland,” behind only San Francisco.

Twenty-seven percent of Seattle renters are also categorized as “looking to leave.”

Interestingly enough, Seattle is the third most popular destination for renters leaving San Francisco, only trailing behind Portland and Salt Lake City.

As for why Seattle renters are headed to Portland, the report cites “some of the nation’s most robust tech sectors” as one of the driving factors.

“The fact that Portland is attracting so much interest from these areas portends continued expansion of the metro’s already growing tech scene, as a subset of workers in San Francisco and Seattle seek out opportunities in places with more affordable housing costs.”
